My Delta force 26 SAW build for P,Q,S

[RaceMechaniX]

Matt,

I believe Flint in going to be the closest SAW event to you. Check with an IMPBA officer for your district and surely they can point you in the right direction. The DF26 is easy to pack in a suitcase and does make a great little SAW boat. I would recommend traveling to one of the bigger SAW events to meet other competitors and talk set-up. As previsously mentioned most SAW racers, myself included keep our set-ups under the radar however almost all of us are very willing to help at events. One strong piece of advice when overpowering these little hulls: make sure you have enough floatation! Even my N2 SAW DF26 which had a lightweight power system stayed submerged for two days in Flint after the cowl untaped. The hull was neutrally bouyant at best, but finally unstuck it self from the mud after being knocked loose with a rake. Your power sysem willl weigh close to twice what mine did.

Howdy, Put a little more time into the boat. Got holes drilled and mounted hardware,antenna, cut flood tube to size and determined where to put motor. I feel like sh*t so I'm going to finish tomorrow. PS the Stuff tube isn't cut yet just for looks.Tomorrow I'll glue and resin it all up. Some pics. 007.jpg003.jpg006.jpg001.jpg

Tyler, Thanks for the info. about events. I'm going to look into it some more when feeling better. Floatation??? Well, I'll show you how we do it in N. Wisconsin. After the ballast setups tomorrow and I'm feeling up to it. I'll show you the proper technique for testing correct floatation amounts!!!! Its a secret but I'll show you cause your so kind!!! and you got some fast boats. Later, MM.

Dana, Looks great!! You'll have more vertical movement than my stinger rig. I was going to use a strut but I just like the looks of a stinger. My pics w/ the motor and tubes aren't correct. It will have a short flood tube like yours but the motor will be very close to the transom. My flex shaft will be only approx. 4" long. I should have the majority done by tomorrow. I'm not feeling the best. Keep up the good work. Remember faster is better!!! Later, MM.

Good Morning, A nice 10 degrees thus morning. Today a high of 33 and a low tonight of -5 w/ a high for Fri. of a nice 7 degrees. Anyway got the flooder complete, total length is of carbon tube is 2.75" inside is the stuffer tube held in be rtv silicone approx. 1/2" plug. This will allow for the slight angle changes required for tuning the stinger(hopefully enough movement) I added a wire harnass cap for looks and support. Also I will discharging the water thru the flood for cooling and ???? I can't think of anything else. The stuffer tube is 7/32 brass tube which IMO is too large for the .150 shaft so I will be appling a special teflon shrink tube w/ lube in the inside and out. This will protect (double lube)and limit the flexy from snaking inside the tube. It will be like a floating flex shaft. It might work!! Also the ID of the tube will allow me to upgrade to a .187 flex since it is almost a straight shot from motor the prop and I'm not using any teflon tube inside. Just in case I start eating up the .150. I'll show you that later. back to glueing.007.jpg002.jpg006.jpg005.jpg008.jpg Here are some pics.

Matt, you might consider angled reinforcing struts for the rudder. It's relatively long in relation to it's mounting footprint. High speed cartwheels, a dreaded but all-too-frequent occurrance in small high speed SAW rigs might create some mayhem.

[maddmatt]

Howdy, I agree!!! We must be reading from the same page. Inside is backed but I'm not sure it going to do the job. Brain storm??? I'll think of something. Not much meat to tie into on the rudder arm. Will we see?? Off to the Docs i go. Got a bad cold. Boat should almost complete today. Got a lot more stuff to post. Thanks, MM. PS Whos a good sticker guy??????????????????

Running to the lake now, but I have an idea for the reinforcing struts I'll send later.

Great sticker guy, easy to self-design :

Thanks and enjoy. We have 16" of ice!! It will be a while till I can play. Matt

Out of curiostity.... Why did you mount the rudder so far to the starboard side?

[maddmatt]

Mr. Rumdog, Very good question. The answer is theres just not enough room. If I move more to port it will not fit bcause of the tabs. Move even more to port and the prop will hit it. I could shorten to stinger or get longer rudder arm. Hopefully it will work. Here are some better pics. Later,MM.019.jpg016.jpg[ATTACH=CONFIG]70124[/ATTACH

Sorry about the photo of my kids race sled. I'll try to remove it later. Back to work. MM

[maddmatt]

OK, I can't get rid of the sled pics. Today I basically finished the boat except some setup(secret!!) and adjustment. I will remove all electronics and place it in the hot tub for floatation check(per Tyler). After that reinstall electronics and batts. and do a floating attitude check. Going to set my CG. Which will a little higher than normal. I'm also going to pour a resin ballast at the valley of the hull. This will lower my cg and help adjust ride and strength. The boat will be leveled in hot tub by adding weight and it will be marked(water line) w/ tape on hull for level. It will be place on my bench leveled from the tape and resin will added. Secret amount!!!. It all depends on several factors. After that setups, I will coat the floor of the hull w/ a special resin w/ transparent fibers for extra strength( I hate clothe). For the hatch, I'm going to add a small piece of foam enough to hold its own weight. Nothing else. I feel it is strong. If you compare it to a MG hatch its Night and Day. I don't believe in adding extra weight on top, it causes a rolling effect!!! Take this small boat w/ a stock hatch and tape a golf ball to the top and run some rollers. Then remove golf ball and run the rollers again. You will see a large difference at high speeds. Just my opinion!!! Top heavy-NO. Extra strength- YES, but 2 ozs or more of weight @ hopefully 80 mph helps the killer chimes!!! And Bammm!! It going to happen regardless. I'm going to push this little boat to the MAXXXX!! Photos to come. Later, MM.
